Due to the depletion of fossil fuels and price fluctuations that threaten the global economy, it is therefore required to use sustainable energy sources including recycling plastics to petroleum-based materials [2].
As a petrochemical material, plastic is very difficult to degrade naturally.
Methodology Materials.
Calorimeter analysis was conducted according to American Society for Testing and Materials (ASTM): Standard Test Method for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter (ASTM D240-19).
Hydrocarbon compounds as potential fuel materials presence in pyrolysis derived oil from bubble wrap plastic waste.

It features properties that enable measurement and testing across various pressure parameters, with particular emphasis on the selection of appropriate materials
For both previous versions [4] and the current version of the model (artificial) eye, further research and development are planned to create a more compact version, as well as to optimize production processes and materials used.
